I like Gale, he is the friendliest companion in the beginning. I normally meet him, after a certain slightly crazy vampire put a knife to my neck, so I really appreciate Gale being polite and friendly. And while he sometimes doesn't have the best ideas, he is one of my favourite companions. If I want a really chill party, I have Gale, Wyll and Karlach with me and leave team drama queen at home. Jaheira works too later in the game.
